I missed it. If you can set it to view the proper levels what is your issue? Sampling them from a shader? If you want to use textureLod, try it without changing the texture parameters. I have used a shader to pick a specific texture level without changing texture parameters.

Sry, I ment it works when rendering with "texture()" [without Lod] and chaching its base level but it doesn't when using "textureLod" without the baselevel midification. Tomorrow I will try commenting out all parameter changes and see what happens.
